Command
Description
.1 FIX? Returns 1 if the pixel specified by the
coordinate in level 1 is on, or 0 if the
pixel is off.
PVIEW Displays PICT with the specified
coordinate at the upper left corner of
the graphics display.
1"■ PX->C Converts a pixel coordinate
C #Hx #Mv > to a user-unit coordinate
C-.PK
C--PX
'.. X S j/ ..■.
Converts a user-unit coordinate y'>
to a pixel coordinate i #?«x
(PRG) GR JB ;
-»GROB (To graphics object.) Converts an
object (level 2) into a graphics object
using real number n (0 to 3 from
level 1) to specify the character size.
The resultant graphics object is a string
of small ( n = l ) , medium ( n = 2 ) , or large
(n=3) characters. For n = 0 , the
character size is the same as for n=3,
except that for algebraic and unit
objects, the resulting graphics object is
the EquationWriter picture.
L : 1 ! -1 BLANK Creates a blank graphics object on the
stack of size #»x (in level 2) by #«y (in
level 1).
i;;;; o
r GOR (Graphics-object OR.) Superimposes
the level 1 graphics object onto the level
3 graphics object. The upper left corner
of the level 1 graphics object is
positioned at coordinates specified in
level 2.
GXOR (Graphics-object XOR.) Same as GOR
except that the level 1 graphics object
appears normal on a light background
and inverse on a dark background.
